Be it known that I, ANDRES G. LUNDIN, a citizen of the United States,residing at Neponset, in the county of Suffolk and State ofMassachusetts, have invented new and useful Improvements in Horseshoes,of which the following is a specification. I

This invention relates to improvements in horseshoes and particularly toa special class of horseshoes having detachable calks, and has for itsobject to provide novel calks which may be conveniently removed whenenabling the calks to To this end, my invention consists in the novelfeatures of construction and in the combination and arrangement of partsset forth in the following specification and particularly pointed out inthe claims.

Referring to the drawings: Figure 1 is a top plan of a horseshoeembodying my invention. Fig. 2 is an enlarged detail sectional viewtaken on line 2-2of Fig. 1. Fig. 3 is an enlarged detail sectional viewtaken on line"3 3 of Fig. 1. Fig. 4- is an enlarged detail sectionalview taken on line H of Fig. 1. Fig. 5 is a perspective view of one ofthe heel calks. Fig. 6 is a perspective view of the toe call.

Like numerals refer to like parts throughout the several views of thedrawings.

horse in pulling a load tends to force the lugs into their respectiveholes and hold them firmly in place, thus taking the strain oft of thepins which hold the lugs in their respective holes, this result, ofcourse, being possible only where the fulcrum is located at the rear ofthe hole.

ier Wlll be smoothly and accurately formed without the necessity ofbeing finished in any way for being assembled and it will, therefore, beapparent that the user may be supplied with a number of toe and heelcalks which will be preferably consisting like 17, 17 passing pins,rivets or the 18, 18 provided in hrough perforations interchangeable andwill thus permit reing upwardly from the first-mentioned replacement ofworn calks in a few moments cess and thence forwardly toward saidpertime by a comparatively unskilled person. foration; a calk having itsbody portion Having thus described my invention, what located'in thefirst-mentioned recess, a hook I claim and desire by Letters Patent toseextending upwardly in the second-mentioned cure is: recess and thenceforwardly therein toward 1.
